Mark this point with care: Those who receive the pure mark of truth, wrought in them by the power of the Holy Ghost, represented by a mark by the man in linen, are those “that sigh and that cry for all the abominations that be done” in the church.30Testimonies for the Church 3:267.
The class who do not feel grieved over their own spiritual declension, nor mourn over the sins of others, will be left without the seal of God....
Not all who profess to keep the Sabbath will be sealed. There are many even among those who teach the truth to others who will not receive the seal of God in their foreheads. They had the light of truth, they knew their Master's will, they understood every point of our faith, but they had not corresponding works....
Not one of us will ever receive the seal of God while our characters have one spot or stain upon them. It is left with us to remedy the defects in our characters, to cleanse the soul temple of every defilement. Then the latter rain will fall upon us as the early rain fell upon the disciples....
What are you doing, brethren, in the great work of preparation? Those who are uniting with the world are receiving the worldly mold and preparing for the mark of the beast. Those who are distrustful of self, who are humbling themselves before God and purifying their souls by obeying the truth—these are receiving the heavenly mold and preparing for the seal of God in their foreheads. When the decree goes forth and the stamp is impressed, their character will remain pure and spotless for eternity.
Now is the time to prepare. The seal of God will never be placed upon the forehead of an impure man or woman. It will never be placed upon the forehead of the ambitious, world-loving man or woman. It will never be placed upon the forehead of men or women of false tongues or deceitful hearts. All who receive the seal must be without spot before God—candidates for heaven.31Testimonies for the Church 5:211, 213-216. Mar 240
We are brought into sympathy with Christ through the fellowship of His sufferings. Every act of self-sacrifice for the good of others strengthens the spirit of beneficence in the giver's heart, allying him more closely to the Redeemer of the world, who “was rich, yet for your sakes ... became poor, that ye through His poverty might be rich.” 2 Corinthians 8:9. And it is only as we thus fulfill the divine purpose in our creation that life can be a blessing to us. SC 79
The Lord said unto him,
Go through the midst of the city, through the midst of Jerusalem, and
set a mark upon the foreheads of the men that sigh and that cry for all
the abominations that be done in the midst thereof. Ezekiel 9:4. KJV
